DJango HttpResponseRedirect not passing "request" to function
I am using the DJango login/authentication functionality. I have extended it with a Profile using the Extending The Existing User Model approach. In the "Profile" is a variable called restrole. In the code below, restrole is being used to control the NEXT screen the user sees (as well as as the data on it): def user_login(request): if request.method == 'POST': # First get the username and password supplied username = request.POST.get('username') password = request.POST.get('password') # Django's built-in authentication function: user = authenticate(username=username, password=password) if user: # Check it the account is active if user.is_active: # Log the user in. login(request, user) myprofile = user.userprofileinfo restrole = myprofile.restrole if restrole == 1: return HttpResponseRedirect(reverse('authinduction:induct-owner')) elif restrole == 2: return HttpResponseRedirect(reverse('authinduction:induct-office')) elif restrole == 3: return HttpResponseRedirect(reverse('authinduction:induct-customer')) elif restrole == 4: return HttpResponseRedirect(reverse('authinduction:induct-field-work')) else: return HttpResponse("Unrecognized Role") This Part works fine I can get data from the "request" variable # First get the username and password supplied username = request.POST.get('username') <<< data is returned password = request.POST.get('password') <<< data is returned The problem When I execute one of the branches: if restrole == 1: return HttpResponseRedirect(reverse('authinduction:induct-owner')) It goes to the correct function, but "request" does not appear to have any data associated … -

How to extend Django filer image model field by category
I recently had problems with extending django filer, probably my knowledge about django is not sufficient yet. Basically what I would like to achieve is to extend django filer image model to be able to add category to images. Of course would be nice to have manytomany relation to category model.

DJango authentication User search not working properly
What I am trying to do is the following: 1. Retrieve a User record (from the DJango authentication system) is in the DB 2. get the Username (from that record) 3. Use the "username" to look for a record in a *different* table. 4. If the record *is not* there (in the *different* table), then create one. I am getting an error on what looks like the query into the User table even though I have the following in the views.py from django.contrib.auth.models import User Also, it is not clear why the DoesNotExist error is taking place (when one is looking for the User in the authentication system).

Django Geojson Serializer does not return any "properties"
I am trying to load PostGIS data to GeoJSON using Django's serializing objects from this reference: GeoJSON Serializer I was able to successfully load the said data to a map with its corresponding geometrie. However the rest of its fields in the model does not exist in its GeoJSON properties field when I checked. Instead of an output: { 'type': 'FeatureCollection', 'crs': { 'type': 'name', 'properties': {'name': 'EPSG:4326'} }, 'features': [ { 'type': 'Feature', 'geometry': { 'type': 'Point', 'coordinates': [-87.650175, 41.850385] }, 'properties': { 'name': 'Chicago' } } ] } If would get: { 'type': 'FeatureCollection', 'crs': { 'type': 'name', 'properties': {'name': 'EPSG:4326'} }, 'features': [ { 'type': 'Feature', 'geometry': { 'type': 'Point', 'coordinates': [-87.650175, 41.850385] }, 'properties': { } } ] } I basically wanted the properties to be included so that I can manipulate it in the Leaflet layers. However, unable to serialize the other fields (or at least a specific field from my model), I won't be able to do this. How can I include for example trail_name in the output GeoJSON properties? models.py class Trail(models.Model): ogc_fid = models.AutoField(auto_created=True, primary_key=True, null=False) trail_name = models.CharField(max_length=100, blank=True, null=True) trail_id = models.CharField(max_length=100, blank=True, null=True) trail_type = models.CharField(max_length=300, blank=True, null=True) wkb_geometry … -

Mommy receipe with m2m not working - 'RecipeForeignKey' object has no attribute 'pk'

ProgrammingError in Django when adding a new model-instance to the Database, what could be wrong?
When using the Django Admin panel, I am able to add new instances to Users and Groups. The same thing goes for all my apps, except for one. This one app, resultregistration, always gives me a ProgrammingError whenever I try to add a new model. For example, this app has a Competition-model where data about a sport competition should be stored. When I click "+ Add" I am taken to the correct site where I can add a new competition. However, when I press save I get: ProgrammingError at /admin/resultregistration/competition/add/ column "competition_category" of relation "resultregistration_competition" does not exist LINE 1: INSERT INTO "resultregistration_competition" ("competition_c... Of course, I assume something is wrong with the migrations. However, I have run python manage.py makemigrations appname, and python manage.py migrate appname, and that works fine. I get a message that there are "No changes detected", and "No migrations to apply". I have tried solutions posted on SO, but none of them worked. What is the general reason for this error? And does anyone know what could be wrong in this specific case? Could one get this error if something is wrongly defined in the model? Or does it have to be a migration problem? … -
How to get property names from super class in sub class python

How can I not need to query the database every time?
How can I not need to query the database every time? From the bellow snapshot: I have five tabs, name as: 云主机,云硬盘,云主机快照,云硬盘快照,安全组: And in the bottom of the list, there is <<, <, >,>>, and GO buttons that can calculate the page_num. Then I can use the localhost:8000/app_admin/myServers-1-1-1-1-1 analogous link to query the data. 1-1-1-1-1 represents 云主机,云硬盘,云主机快照,云硬盘快照,安全组's page_num. In the views.py, there are key codes: def myServers(request, server_nid,disk_nid,snapshot_server_nid, snapshot_block_nid,security_group_nid, tab_nid): data = get_res_myserver(request, server_nid,disk_nid,snapshot_server_nid, snapshot_block_nid,security_group_nid, tab_nid) return render(request, 'app_admin/my-server.html', {"data":data}) ... def get_res_myserver(request, server_nid,disk_nid,snapshot_server_nid, snapshot_block_nid,security_group_nid, tab_nid): # query all the data, and paginator there ... return data But, my issue is, every time I query the localhost:8000/app_admin/myServers-x-x-x-x-x, it will take a long time, sometimes more than 8 seconds(the time can not be shorter), its a long time for user experience. So, Whether there is a method that I only query my data once, then paginator can be multiple times? -
